A comment on rotons in two-dimensional liquid helium II

A comment on rotons in two-dimensional liquid helium II The spectrum of rotons in two-dimensional liquid helium II is estimated within the Bijl-Feynman theory. Due to stronger short-range order and more effective back flow, the roton gap Δ is found to be about half as big as the bulk roton energy. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Low Temperature Physics Springer Journals

Abstract

The spectrum of rotons in two-dimensional liquid helium II is estimated within the Bijl-Feynman theory. Due to stronger short-range order and more effective back flow, the roton gap Δ is found to be about half as big as the bulk roton energy.
